Self-control suspension back pack based on motion perception and acquisition method for optimal effective length

Abstract

The invention discloses a self-control suspension back pack based on motion perception and an acquisition method for optimal effective length. The device comprises a main body frame, a sliding module,a back pack rack, a pulley block, an elastic rope, a second detection unit, a clamping module, a drive module, a control module, a power supply, a first tension and pressure sensor and a second tension and pressure sensor, wherein the sliding module slides along the main body frame; the back pack rack is connected with the sliding module; two ends of the first tension and pressure sensor are connected with the sliding module and the elastic rope respectively; the elastic rope passes through the pulley block and the clamping module; the elastic rope is connected with the second tension and pressure sensor; the drive module is used for driving the clamping module; the power supply is used for supplying power for the drive module and the control module; the pulley block and the clamping module are connected with the main body frame respectively; and the control module is used for adjusting an optimal rope length so as to send a rotating command to the drive module. According to the method, stepwise regression is established in a cross multiplication form according to independent variable interaction and high-order influence, and the optimal effective length is acquired through variance analysis; and according to the method, the load impact can be alleviated.

Description

technical field [0001] The invention belongs to the field of human body loads, in particular to a self-controlled suspension back frame based on motion perception and a method for obtaining an optimal effective length. Background technique [0002] In application scenarios such as mountaineering, hiking and other sports, as well as soldiers carrying on the battlefield, users often need to carry a large load for exercise, resulting in excessive physical exertion of the user, and even fatigue damage. At present, to solve the problem of the user's heavy load, mainly through optimizing the structure of the backpack to improve the pressure distribution, adding cushioning materials at the contact parts to reduce the local pressure, or using external auxiliary tools such as trekking poles, individual exoskeletons, etc. to provide users with Extra support or motivation. However, the optimization of the backpack structure can only relieve the human body when carrying a large mass lo...

Problems solved by technology

However, the optimization of the backpack structure can only relieve the human body when carrying a large mass load. Complex tools such as exoskeletons have the disadvantages of excessive weight and high energy consumption.

In response to this reality, people try to use other technical approaches to improve the impact on the human body during heavy-load exercise. Among them, the HoverGlide company in the United States proposed a floating backpack based on the principle of labor-saving shoulder poles. The vertical direction is asynchronous during the movement, but this backpack cannot realize the dynamic adjustment of the effective working length of the elastic rope under different movement characteristics
